Synopsis: Zero: Circle of Flow

Gi Yuh leads the strongest gang in his high school and resides with his affectionate younger sister. While rescuing the striking Ha Na from a reckless truck, he ends up injured and succumbs to a coma for a fortnight. Within this period, he delves into an unfamiliar dream world, which alters him permanently after he recovers. He periodically dreams of his previous self, prompting him to ask his teacher for aid. His teacher possesses acquaintances who specialize in sources of predicting future events and paranormal abilities, and with their help, he discovers a bizarre truth: he is meant to be an elevated phantom who assumes the identity of deceased or imminently dying individuals.
